Liquid crystal display apparatus

Abstract

A liquid crystal display apparatus includes a display unit, a drive rod, and an adjusting module. The display unit is for displaying information. The drive rod is connected to the display unit for moving along with the display unit. The adjusting module is connected to the drive rod, for rotating the drive rod.

1. A liquid crystal display apparatus comprising:
 a display unit for and displaying information; 
 a drive rod connected to the display unit for moving along with the display unit; and 
 an adjusting module connected to the drive rod, for rotating the display unit by the drive rod to adjust a viewing angle of the liquid crystal display apparatus; 
 wherein the adjusting module comprises a sheet connected to the drive rod, a first ferromagnet connected to a left end of the sheet, a second ferromagnet connected to a right end of the sheet, a first electromagnet disposed near the first ferromagnet, and a second electromagnet disposed near the second ferromagnet; the first electromagnet is used for receiving the voltages to generate a first magnetic field to attract the first ferromagnet, and the second electromagnet is used for receiving the voltages to generate a second magnetic field to attract the second ferromagnet. 
 
     
     
       2. The liquid crystal display apparatus according to  claim 1 , further comprising a power supply for supplying the voltages. 
     
     
       3. The liquid crystal display apparatus according to  claim 2 , further comprising a receiver for receiving a signal instructing the liquid crystal display apparatus to display information. 
     
     
       4. The liquid crystal display apparatus according to  claim 1 , further comprising a controller for modulating the voltages based on the signal. 
     
     
       5. The liquid crystal display apparatus according to  claim 1 , further comprising a transparent layer near a display surface of the display unit. 
     
     
       6. A liquid crystal display apparatus comprising:
 a receiver for receiving a signal instructing the liquid crystal display apparatus to display information; 
 a display unit for displaying information; 
 a drive rod connected to the display unit for moving along with the display unit; and an adjusting module connected to the drive rod, for rotating the display unit by the drive rod to adjust a viewing angle of the liquid crystal display apparatus; 
 an adjusting module for rotating the display unit based on the signal, the adjusting module comprising: 
 a sheet connected to the display unit; and 
 at least one ferromagnet and at least one electromagnet for cooperatively driving the sheet to move; 
 wherein the sheet is used for rotating the display unit when driven by the at least one ferromagnet and the at least one electromagnet. 
 
     
     
       7. The liquid crystal display apparatus according to  claim 6 , wherein the at least one ferromagnet comprises a first ferromagnet and a second ferromagnet connected to two ends of the sheet respectively. 
     
     
       8. The liquid crystal display apparatus according to  claim 7 , wherein the at least one electromagnet comprises a first electromagnet disposed near the first ferromagnet and a second electromagnet disposed near the second ferromagnet. 
     
     
       9. The liquid crystal display apparatus according to  claim 7 , further comprising a controller connected to the first electromagnet and the second electromagnet, and the controller is for sending a first voltage to the first electromagnet and for sending a second voltage to the second electromagnet. 
     
     
       10. The liquid crystal display apparatus according to  claim 9 , further comprising a power supply connected to the controller for sending a voltage to the controller. 
     
     
       11. The liquid crystal display apparatus according to  claim 6 , further comprising a drive rod connected to the display unit and the sheet.
